Product details
Overview
AD7610BSTZ from Analog Devices is a 16-bit, 250 kSPS PulSAR® successive approximation register (SAR) ADC with programmable unipolar/bipolar input ranges (0 V to 5 V, 0 V to 10 V, ±5 V, ±10 V), on-chip 5 V reference (±3 ppm/°C drift), and dual parallel/serial (SPI-/QSPI™-/MICROWIRE™-compatible) interface. It delivers ±1.5 LSB max INL, 94 dB SNR at 2 kHz, and operates across −40°C to +85°C in industrial data acquisition systems.
For engineers reviewing the AD7610BSTZ datasheet, AD7610BSTZ pinout, AD7610BSTZ application, or AD7610BSTZ equivalent, key selection considerations include its hardware/software-configurable input range, no-pipeline-delay SAR architecture, iCMOS® high-voltage process enabling ±15 V analog supplies, integrated temperature sensor output (311 mV @ 25°C), and dual 48-lead LQFP/LFCSP packaging options.
Technical Context
The AD7610BSTZ implements a charge redistribution SAR architecture with internal conversion clock, error correction circuitry, and configurable analog front-end-supporting true bipolar operation via dedicated BIPOLAR/TEN pins and selectable reference modes (internal 5 V or external 4.75 V–AVDD). Its iCMOS® process integrates high-voltage analog rails (VCC = +15 V, VEE = −15 V) with low-voltage digital I/O (OVDD = 2.7–5.5 V).
It features two independent digital interfaces: 16-/8-bit parallel bus with BYTESWAP control and flexible serial modes-including master (internally clocked SDCLK) and slave (externally clocked) configurations-with programmable SYNC polarity, SDCLK edge sensitivity, and daisy-chain capability via SDIN/SDOUT. Configuration occurs either through hardware pins or a dedicated 16-bit serial configuration port (SCCS/SCCLK/SCIN).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7621BRUZ | 16-bit, 2.5 MSPS, true differential input only; no unipolar range support; requires external reference. | Better suited for high-speed differential sensor interfaces (e.g., LVDT, resolver) but lacks AD7610BSTZ's programmable unipolar/bipolar flexibility. | Select AD7621BRUZ when sampling rate >1 MSPS and input is inherently differential; retain AD7610BSTZ for mixed-range legacy analog systems. |
| AD7606BSTZ | 8-channel, simultaneous sampling, 16-bit, 200 kSPS/channel; internal reference; parallel/serial interface; lower power (65 mW @ full rate). | Optimized for multi-channel data loggers and motor control feedback; lacks AD7610BSTZ's single-channel speed and iCMOS® high-voltage tolerance. | Choose AD7606BSTZ for channel density and simultaneous acquisition; choose AD7610BSTZ for higher per-channel throughput and ±15 V analog supply compatibility. |
Compared with AD7621BRUZ and AD7606BSTZ, the AD7610BSTZ uniquely balances single-channel speed (250 kSPS), input range versatility (four hardware-selectable modes), and high-voltage analog integration (±15 V supplies), making it optimal for upgrade paths in legacy industrial DAQ and test instrumentation where layout reuse and supply compatibility are critical.

FAQ
What input voltage ranges does the AD7610BSTZ support, and how are they selected?
The AD7610BSTZ supports four input ranges: 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V. Selection is achieved via hardware (BIPOLAR and TEN pins) or software (serial configuration register). Hardware selection allows immediate range setting at power-up without host processor intervention-critical for standalone data loggers and field instruments where firmware boot time must be minimized. The AD7610BSTZ datasheet specifies exact logic combinations for each range in Table 6.
Does the AD7610BSTZ require an external reference, or does it include an internal one?
The AD7610BSTZ includes a 5 V internal reference with ±3 ppm/°C typical drift and 10 ms turn-on settling time (with 22 μF capacitor). It can operate with this reference enabled (PDREF = PDBUF = low) or disabled (PDREF = PDBUF = high) to accept an external reference from 4.75 V to AVDD + 0.1 V. The AD7610BSTZ reference buffer (enabled via PDBUF) also supports external 2.5 V inputs to generate 5 V on REF-offering design flexibility without adding discrete op-amps.
What is the significance of the iCMOS® process used in the AD7610BSTZ?
The iCMOS® process integrates high-voltage analog circuitry (supporting ±15 V supplies on VCC/VEE) with low-voltage CMOS digital logic (2.7–5.5 V OVDD), enabling the AD7610BSTZ to directly interface with industrial sensors, isolation amplifiers, and actuator drivers without external level shifters. This reduces component count, improves noise immunity, and simplifies power domain partitioning-key advantages confirmed in Analog Devices' AD7610BSTZ application notes for PLC and motor drive designs.
Can the AD7610BSTZ operate in both parallel and serial interface modes simultaneously?
No-the AD7610BSTZ operates exclusively in either parallel or serial mode, selected by the SER/PAR pin. When SER/PAR = low, all D[0:15] pins function as parallel data outputs; when SER/PAR = high, selected D-pins repurpose as serial interface signals (SDOUT, SDCLK, SYNC, etc.), while others go high-impedance. This hardwired mode separation ensures signal integrity and eliminates contention-verified in the AD7610BSTZ timing diagrams (Figures 35–45) and confirmed by its pin multiplexing table.
How does the AD7610BSTZ handle temperature monitoring, and what is its accuracy?
The AD7610BSTZ integrates a calibrated analog temperature sensor outputting 311 mV at 25°C with 1 mV/°C sensitivity and 4.33 kΩ output impedance. It is enabled only when the internal reference is active (PDREF = PDBUF = low). Accuracy is specified as ±1°C over −40°C to +85°C after system-level calibration-documented in the AD7610BSTZ "Temperature Sensor" section (Page 27) and validated in typical performance curves (Figure 32).
